JOHN H. STAMP, OF WHEELING, WEST VIRGINIA.

SPECIFICATION forming part of Letters Patent No. 228,227, dated June 1, 1880. Application filed October 27, 1879.

. West Virginia, have invented certain new and useful Improvements in Bungs; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same,

reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a method of tapping barrels of beer and other liquids and entering a faucet therein Without permitting the escape either of gases or liquid tlierefrom, and also effect a saving of the bungs, which, in the present system of tapping, are forced into the keg and rendered totally unfit for further use.

The invention consists in the construction, arrangement, and combination of the several parts, as fully hereinafter explained.

In the drawings, Figure l is a side view of the hollow bung; Fig. 2, atransverse section on line 00 m, and Figs. 3 and 4 lengthwise central sections.

he bung is made in two cylindrical sections, A A, and secured to each other at a suitable distance apart with pins 1) b b. The section A is made with a tubular bore, 0, a portion of its length, of suitable size for the receival of a spiral spring, d. The section A is made with a tubular bore its entire length, the outer end having an interior screw-thread, the inner end being slightly beveled on the edg the bore in both sections being of suitable size, shape, and proportion for the working therein of a hollow-ended stem or slidevalve, 13. The stem B is enlarged into an annular tapering collar, 6, which fits into the end of the bore in the bung A, making a close joint, the outer portion of the stem being made with a tubular bore, E, which terminates with a vent, g, just back of the collar e.

The spring 01 operates to keep the tapering collar 0 on the stem B tight against the end of the bung A, and thus prevent the exit of the fluid during transportation or when not on tap.

In Fig. 4 is shown the position of the valvestem when the faucet is inserted in the end of the bung. D is the keg. O is the faucet.

In tapping a keg of beer or other fluid the faucet is simply screwed into the outer end of the bung a sufficient distance to force the stem B endwise until the vent passes the end of the bung A far enough to permit the flow of the contents.

In the construction of the bung I contemplate nickel-platiug the spiral spring to prevent corrosion. The other portions I intend making of wood, although I do not wish to confine myself to that material or to the exact. construction herein shown, as it is obvious that other material and other modes of construction suitable to the material could be used which would be within the scope of my invent1on.

The exterior of the bung may be screwthreaded, for convenience and security in attaching it to the barrel-head, and in some cases it may be desirable to omit theinterior screwthread and use a smooth tapering spigot, and driving the same into the hung with a mallet or other suitable instrument.

The collar e on the stern B may be faced with rubber or other suitable material, if found necessary, to secure a hermetically-tight joint, all of which I consider modifications of my invention.

The advantages arising from the convenience in tapping kegs of beer or other liquid provided with this device, the great saving of bungs, and the consequent labor of fitting in new ones, are apparent, and need not specially be referred to.

Having described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination of the sections A A, connecting-pins b b b, stem B, having taperin g enlargement c, and spring d, substantially'as herein shown, and for the purposes set forth.

2. The described bung or tap for barrels,

consisting of two cylindrical sections, A A, In testimony that I claim the foregoing as connected by pins, a spring-actuated valve, my own Ihereunto afiix my signature in pres- 10 B, having flange 6, adapted to bear against ence of two witnesses.
